Patented Man 28, 1922.

@riginal application led January 30, 1919, Serial No. 273,957. Dividedand this application filed June 11, 1920. Serial No. 38,107.

To all whom t may concern Be it known that I, Louis A. SUEKOFF, acitizen of the United States, residing at Chica-go, `in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Spring-Cushion Constructions, of which the following isa specification.

This invention relates to improvements in spring cushion constructionsadapted for incorporation in seat and mattress structures, and thepresent application is a division of my former application which wasissued as Letters Patent of the United States No.

1,397,021, dated November 15, 1921.

The object of the present invention 1s to provide a construction of thischaracter wherein maximum economy may be effected in the amount ofmaterials producing the same.

Furthermore, the invention also contemplates the provision of a novelform and arrangement of the spring units and their envelopes, wherebybut a single ply of material is present between contiguous springs, thuseliminating unnecessary use of the fabric of the envelopes and at thesame time providing the requisite separation of the springs to preventtheir contact with each other. The sound of the springs in theirrelative movement with respect to each other is thereby precluded, whilematerial saving in the textile fabric of the envelopes or covering forthe springs is efected.

Other objects and advantages will appear as the nature of theimprovements is better understood, the invention consistingsubstantially in the novel construction, combination and arrangement ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and finally pointed out in the appended claims.

In the drawings- Fig. 1 is a top plan view of the hereindescribedinvention, the springs being illustrated in dotted lines.

Fig. 2 is a detail vertical transverse sectional view on the line 2-2,Fig. 1.

Fig. 3 is a similar view on the line 3 3, Fi 1.

ig. 4 is a detail perspective view of the envelopes, broken away, forone series of the snrlnfrs.

Refierring now in detail to the accompanyemployed when ing drawings, itwill be observed that the hereindescribed spring cushion construction ismade up of a plurality of individual springs properly separated fromeach other to prevent contact of the several springs so that they maymove independently, and likewise without the .metallic sound thatemanates from the rubbing action of their coils upon each other. Itincludes a plurality of independent unitary envelopes or pockets, eachspring having its individual envelope or pocket, as most clearlyillustrated in Fig. 4. Each of these pockets is formed of a single stripof material 1() which includes vertical side walls 11, a bottom 12, anda top 13, and the ends of said strip, which ends are the terminalport-ions of one of the side walls 11 and the top 13, are connected, asat 14, as by stitching or equivalent fastening means. A spring 15occupies each of the envelopes or pockets, and the expansive force of.said springs exerts stretching act-ion upon the pocket or envelope sothat the side walls thereof are properly tensioned. In assembling theseenvelopes or pockets they are so arranged that each of the envelopes orpockets is disposed at right angles to the envelopes contiguous thereto,which arrangement is clearly illustrated in Fig. 4. ln this manner theside walls 11 serve to close the open portions of the envelopes ofcontiguous pockets, and the ends of the several pockets are fastenedtogether along their marginal portions 16, as by stitching or equivalentfasten` ing means, thereby uniting the several envelopes or pockets intoan integral structure.

ln unlting the several pockets in the manner above described it will beAunderstood that the cushion construction may be extended to any desireddimension. A single ply only of the material is employed for each of thepockets, and at each side thereof, and by disposing the contiguo-uspockets at right angles to each other economy of material is effec-ted,due to the open sides of each. pocket being closed by the material ofthe adjacent pockets located at right angles thereto. The springs areprevented contacting with each other so that their relative movement maybe had without the coils of contiguous springs being brought together orrubbing directly against each other. inasmuch as the walls of thepockets are connected only at their top and bottom marginal portions,the inter mediate edges being free, access may be readily had to eachindividual pocket for inserting the springs into and removing the sametherefrom.

I claim:

1. A spring cushion construction of the class described, comprising aplurality of independent lunitary envelopes or pockets each of which isarranged at right angles to the adjacent pockets, two of the oppositesides of each of said pockets being open, and

a spring arranged within each of said pock ets, the open sides of eachof said pockets being closed by'the closed sides of the pock etscontiguous thereto, the ends of the several pockets being connectedalong their marginal portions to imite the pockets into an integralstructure.

2. A spring cushion construction of, the class described, comprising a.plurality of independent unitary envelopes or pockets each of which isformed of a strip of material connected at its ends and includingvertical side walls, a top, and a bottom, the opposite sides of each ofsaid pockets heilig open, and a spring arranged in each of said pockets,each pocket being arranged at right angles to the adjacent pockets,whereby the vertical Side walls ot each pocket serve to close the opensides of the adjacent pockets, said vertical side walls separating therespective springs from contact with each other, the ends of the severalpockets being connected along their marginal portions to unite thepockets into an integral structure.

In testimony whereof l have hereunto signed my name in the presence oftwo subscribing witnesses.
